SWEEP MECHANISM FOR BALING-PRESSES.

Specification of Letters Patent.

Application filed June 8, 1911.

Patented Dec. 10, 1912.

Serial No. 632,045.

To all whom it may concern:

Be it known that I, EDWARD H. SHOLAR, a citizen of the United States,residing at Chattanooga, in the county of Hamilton and State ofTennessee, have invented a new and useful Sweep Mechanism for Baling-Presses, of which the following is a specification.

This invention has relation to sweep mechanisms for baling presses andconsists in the novel construction and arrangement of its parts ashereinafter shown and described.

The object of the invention is to provide a sweep mechanism adapted tobe used in the capacity stated which is simple in struc ture, powerfulin its action and which may be readily operated at the expenditure of aminimum amount of energy.

In the accompanying drawing: Figure l is a top plan view of the balingpress with the sweep mechanism applied thereto. Fig. 2 is a sideelevation of the same. Fig. 3 is an enlarged plan view of the sweepmechanism with parts removed showing the plunger rod in projectedposition. Fig. 1 is a similar view of the sweep mechanism showing theplunger rod in retracted position. Fig. 5 is a similar view but on asmaller scale showing the plunger rod in the act of being projected.Fig. 6 is a perspective view of the under side of an arm forming a partof the sweep mechanism. Fig. 7 is a perspective view of a lever whichalso forms a component part of the sweep mechanism. Fig. 8 is atransverse sectional View of the sweep mechanism,

The baling press consists of a baling box 1 which may be of any usualpattern having a plunger 2 mounted for reciprocation therein. An axle '8is located under the intermediate portion of the baling box 1 and at apoint between its ends carries a sleeve 4:- The baling box 1 is providedupon its under side and in the vicinity of its end with a sleeve 5 andthe sleeves 4 and 5 loosely receive the rear end portion of a sill 6. Acuff 7 is adjustably fixed to the sill 6 by means of a bolt 8 and isprovided with a flange 9 which is located at one side of the sleeve 5while the body portion ofthe said cuff is located at the opposite sideof the said sleeve. Thus it will be seen that means is provided forshifting the sill 6 with relation to the sleeves 4: and 5 and securingthe said sill 6 with relation to the said sleeves against longitudinalmovement but permitting the said bar to turn within the sleeves. At itsforward end the sill 6 is attached to a plate 10 and is fixedly held inrelation thereto by means of braces 11 which are connected at their rearends with the said reach bar and at their forward ends with said plate.

The plate 10 is provided with an upstanding concentric pintle 12 and isprovided upon its upper side with a stop 13. The plate 10 is providedupon its under side with a bearing block 14 which rests upon theintermediate portion of an axle frame 15 which is pivotally secured tothe said block by means of a pivot bolt 16. An arm 17 is pivoted at oneend upon the pintle 12 and is provided at its inner end with a set ofgear teeth 18. At a point between its ends the arm 17 is provided with alug 19 in the path of movement of which is located the stop 13 upon theplate 10. At its outer end the arm 17 is pivotally connected with a shoe20 carried at the forward end of a plunger rod 21. The said rod at itsother end is pivotally or appropriately connected with the plunger 2which is located for reciprocation within the baling box 1. An arm 22 isprovided upon its under side and at a point midway between its ends witha bearing 23 which is journaled upon the upper end portion of the pintle12. The said arm 22 is provided upon its under side and in the vicinityof its ends with freely journaled rollers 24:. A disk 25 is provided atone side with a-series of gear teeth 26 which mesh with the gear teeth18 carried at the upper end' of the lever arm 17 and the said disk isprovided at its side opposite that side at which the teeth 26 arecarried with a projecting lug 27 which at times is located in the pathof movement of the rollers 214: carried by the arm 22.

A sweep pole 27 is provided at its inner end with a head 28 which ispivotally and resiliently connected with one end of the arm 22. The pin29 is carried by the arm 22 and passes up through the head 28 and a coilspring 30 is interposed between the head of the pin 29 and the uppersurface of the head 28 and bears down upon the said head 28 and has atendency to hold the same in close contact with the upper surface of thearm 22. A brace rod 31 is connected at one end with that end of the arm22 opposite the end thereof to which the sweep pole 27 is connected andat its outer end the brace rod 31 is adjustably connected with the outerend portion of the sweep pole 27 by means of nuts 32 which are screwthreaded upon the outer end portion of the rod 81 and re ceive betweenthem a sleeve 38 which is fixed to the outer end portion of the sweeppole 27 i The operation of the sweep mechanism is,

as follows. Presuming that the parts are approximately in the positionsas illustrated in Fig. 1 of the drawing the plunger rod 21 is in itsretracted position and the draft animals which are hitched to the outerend of the sweep pole 27 are about to pass at their fore legs over theplunger rod 21 and sill 6. As the animals move over the said sill 6 androd 21 the arm 22 is turned upon the pintle 12 and when the animals havepassed entirely over the said sill 6 and rod 21 the rod 21 is thensubjected to the compression stress of the plunger 2 to which it isconnected. In the meantime the hay. has been fed into the baling box 1and the said plunger 2 engages the same and compresses the same into thebaling chamber of the said box. As the said arm 22 is continued in itsrotating movement upon the pintle 12 the rod 21 is pushed to theposition as illustrated in Fig. 3 of the drawing when the plunger 2attached to the end thereof is at the extent of its compression strokewithin the baling box 1. At this time the roller 24 at the opposite endof the arm 22 engages the lug 27 at the side of the disk and as the saidarm continues to rotate the said disk 25 is rotated upon its pivotalconnection with the plate 10 and through the intermeshing gear teeth 26and 18 the arm 17 is rotated and carries back with it the shoe 20 andthe plunger rod 21 to the position as illustrated in Fig. 4 of thedrawing. When the parts are thus positioned the roller which haspreviously been in engagement with the lug 27 upon the disk 25 passes tothe shoe 20 and again forces the rod 21 in a direction toward the balingbox 1. Thus the lever 17 and arm 22 are mounted for pivotal or rotarymovement upon a common axis which materially simplifies the structureand renders the action of the apparatus positive. 7

When it'is desired to transport the sweep mechanism and baling press towhich it is attached from one point to another, supporting wheels arejournaled'upon the axles 3 and 15 and the arm 22 is turned so that theplunger rod 21 is projected to the extent of itscompression stroke asillustrated in .Fig. 3. When this is done the sweep pole 27 and brace 31are in the positions as indicated in heavy lines in" Fig. The said willbe received in the box 1. The bolt 8 is then replaced in the cuff 7 andpassed through the sill and thus the parts are coupled close togetherfor transportation. As the sweep mechanism and the press pass along aroadway they are guided by turning the axle 15 on the plate 10 in theusual manner and by reason of the fact that the baling press 1 may swingor turn upon the rear portion of the sill 6 the sweep mechanism andattached baling press may pass evenly and smoothly over unequal surfacesupon a road bed.
